I have two set matrix defined below:
They contain p values from t-tests between two variables (I know this is bad statistical practice)
I'm trying to use a correlation plot from the corrplot
package to plot them
however, when I use the following line:
corrplot(weird, insig = "p-value", p.mat = weird, type = "lower", sig.level = 1-0.95, method = "circle", is.corr = FALSE, cl.lim=c(0,1), tl.offset=0.4)
The normal matrix displays correctly, yet the weird one doesn't.
This has caused me many hours of frustration, and I have narrowed the problem down to the insig="p-value"
argument, as the corrplot function works as intended without it.
weird<-structure(c(2.22044604925031e-16, 0.018443376602325, 2.12390642555483e-12,

The weird one

Okay, I've worked it out.
There weren't any p-values greater than that required by sig.level
all of them were less than 0.05. As soon as I edited one value to be greater than 0.05 it made it work
eg.
weird[1,1] <- 0.1
corrplot(weird)
works
